Original Ray-Ban RB3706 Replacement Lenses

Original Ray-Ban RB3706 replacement lenses

If your Ray-Ban RB3706 lenses are scratched, chipped or broken, you do not need to replace the whole frame. These original Ray-Ban 3706 replacement lenses restore the look, optical quality and sun protection of your sunglasses at a much lower cost than buying a new pair. At ReplacementLenses.net we are an official EssilorLuxottica distributor, with free shipping and our own optical workshop in Granada.

Model compatibility

These Ray-Ban replacement lenses are made for the Ray-Ban RB3706. They are designed for adult sunglasses with a metal frame, Pillow lens shape and Base 6 lens curvature. For a correct fit, the model code engraved or printed inside the temple must match RB3706 and the right size must be selected.

Because these are original Ray-Ban lenses, the lens geometry, edge profile and curvature are made to sit properly inside the metal rim of the frame.

How to identify your model and size

Open one temple arm and look for the printed reference. You should see RB3706 followed by numbers. The most important code is the model, RB3706, followed by the eye size, which is the lens width in millimetres.

This product is available in sizes 54 and 57. Depending on the variant, lens diameter measurements include 57 mm and 60 mm. If the print on the temple is worn, measure the width of your current lens with a ruler and avoid guessing; with metal frames, even a small size error can affect the fit.

Material, protection and lens finishes

These Ray-Ban RB3706 lenses are made of glass, a premium material valued for its optical clarity, solid feel and scratch resistance compared with standard plastic materials. Every option provides UV400 protection, blocking 100% of UVA and UVB rays.

If you want glare reduction for driving, water or bright reflective surfaces, choose a lens option clearly marked as Polar, such as S2 – Polar blue – Glass or O9 – Polar green AR blue – Glass. Original polarized Ray-Ban lenses carry the Ray-Ban P logo.

Why replace only the lenses

The metal frame of the Ray-Ban RB3706 is built to last. Replacing only the lenses lets you refresh your sunglasses for up to 60% less than buying a new pair, while reducing waste and keeping the frame that already fits you.

It is a smart repair: you keep your original Ray-Ban frame, restore sun protection and avoid paying for a complete pair when only the lenses need replacing.

Frequently asked questions

Are these lenses compatible with my Ray-Ban RB3706?
Yes, they are made specifically for the Ray-Ban RB3706. Check the temple code and select the correct size, 54 or 57.

Are they glass or plastic?
The product specifications list the lens material as glass. This is ideal if you want to maintain the premium feel and optical clarity of original Ray-Ban lenses.

How do I know which size to order?
The size is usually printed inside the temple after the RB3706 model code. If the numbers are faded, measure your current lens width in millimetres before ordering.

Are polarized lenses available?
Yes, but only in the options marked as Polar: S2 and O9. If polarization is important to you, make sure you select one of those lens options.

Do they have the Ray-Ban logo?
Yes, because these are original Ray-Ban lenses. Polarized versions carry the Ray-Ban P logo.

Can I install them at home?
The RB3706 is a metal frame, so the rim is usually opened with a small screw. If you are not used to optical screws and glass lenses, we recommend professional installation.

Is replacing the lenses worth it?
Yes, especially if your frame is still in good condition. You save money, keep your original Ray-Ban sunglasses and make a more sustainable choice.
